I have seen demos and videos of people using VS2012 and getting the intellisense to show the available css tags from their included css files.
i.e. <div class="bt"></div> When I start typing "bt" I get a list of classes in my css files that begin with or contain "bt"
Is this capability built into VS2012 or do they have some third party tool or extension installed? And if it is part of the base VS2012 how do I get it to work again on mine?
